Exactly, it's your brain trying to cope!!!
I think this author must have looked into some things before writing it, because some of it makes sense for people who go through traumatic things.

I see a lot of people hating on Woojin. I'm not excusing him for what he did, but I will say from experience that when something like those things happen back to back, your mind takes over and does things to keep you from totally losing it. When you lose someone, say like his sister, the way he did, that alone is enough to cause memory loss. Add to that, what happened to his friend and yeah he was on overload. Through the manga he starts to remember and that's how the mind is getting back to normal. Little things come back. Hell, I still can't remember everything that happened over the course of a year when I lost someone close to me tragically.
